본 발명은 전자제어식 주차 브레이크에 관한 것으로서, 더욱 상세하게는 차량의 제동시 주차 케이블에 가해지는 힘의 세기를 검출하는 센서의 구조를 단순화한 센서유닛 및 이를 구비하는 전자제어식 주차 브레이크에 관한 것이다.The present invention relates to an electronically controlled parking brake, and more particularly, to a sensor unit that simplifies the structure of a sensor for detecting the strength of a force applied to a parking cable when a vehicle is braked, and an electronically controlled parking brake having the same.

일반적으로, 전자식 주차 브레이크(Electronic Parking Brake : EPB)는 주차 브레이크의 구동을 전자적으로 제어하는 장치이다. 즉, 전자적으로 차량의 휠에 제동력을 가하여 휠이 회전하지 못하도록 하는 장치이다.In general, an electronic parking brake (EPB) is a device that electronically controls the driving of the parking brake. That is, the electronic device applies a braking force to the wheel of the vehicle to prevent the wheel from rotating.

이러한 전자식 주차 브레이크는 주차 케이블에 작용하는 장력 및 변위를 감지하기 위하여 포스센서를 구비하게 된다. 이때, 포스센서는 마그네트를 구비하여 마그네트에 의한 자장변화를 감지하는 홀 IC를 통해 신호가 출력된다.The electronic parking brake is provided with a force sensor to detect the tension and displacement acting on the parking cable. At this time, the force sensor is provided with a magnet through which the signal is output through the Hall IC for detecting the magnetic field change by the magnet.

도 1은 전자식 주차 브레레이크의 동력변환유닛(10)과 포스센서(20)의 결합상태를 나타내는 도면이다.1 is a view showing a coupling state of the power conversion unit 10 and the force sensor 20 of the electronic parking brake.

도 1을 참조하면, 포스센서(20)는 회전운동을 직선운동을 변환하는 동력변환유닛(10)에 설치되어 주차 케이블(C)이 받는 힘의 세기를 측정하게 된다.Referring to Figure 1, the force sensor 20 is installed in the power conversion unit 10 for converting the rotational movement of the linear motion to measure the strength of the force received by the parking cable (C).

동력변환유닛(10)은 모터(미도시)의 회전력을 감속하는 감속기어유닛(미도시)과 연결되어 회전운동을 직선운동으로 변환하는 역할을 한다. 이러한 동력변환유닛(10)은 일측에 주차 케이블(C)이 연결된 스크류부재(11)와, 스크류부재(11)의 축 방향을 따라 스크류부재(11)와 상대운동하는 너트부재(12) 및, 너트부재(12)의 외주면에 결합되어 너트부재(12)와 함께 회전하는 기어부재(13)를 구비한다.The power conversion unit 10 is connected to a reduction gear unit (not shown) that decelerates the rotational force of the motor (not shown) and serves to convert the rotational movement into a linear movement. The power conversion unit 10 has a screw member 11 connected to the parking cable (C) on one side, a nut member 12 relative to the screw member 11 along the axial direction of the screw member 11, and It is provided with a gear member 13 coupled to the outer circumferential surface of the nut member 12 and rotating together with the nut member 12.

너트부재(12)는 중공으로 이루어져 있고, 스크류부재(11)는 이 중공에 회전 나사 방식으로 결합되어 너트부재(12)와 상대운동하며 주차 케이블(C)을 동작시킨다. 너트부재(12)의 타단에는 주차 케이블(C)에 작동하는 제동력을 측정하기 위한 포스센서(20)가 설치된다.The nut member 12 is made of a hollow, and the screw member 11 is coupled to the hollow in a rotating screw manner to move relative to the nut member 12 to operate the parking cable C. The other end of the nut member 12 is provided with a force sensor 20 for measuring the braking force acting on the parking cable (C).

포스센서(20)는 도 2에 도시된 바와 같이, 마그네트(24)와의 위치 이동을 통한 자력 세기 변화를 감지하는 홀 IC(22)가 설치된 센서 하우징(21), 센서 하우징(21)의 일측에 고정된 래치(26), 센서 하우징(21)의 내부에 마련되고 마그네트(24)가 설치된 마그네트 하우징(23) 및, 마그네트 하우징(23)과 센서 하우징(21) 사이에서 센서 하우징(21)을 탄성 지지하는 탄성부재(25)를 구비한다.As shown in FIG. 2, the force sensor 20 is provided at one side of the sensor housing 21 and the sensor housing 21 in which the hall IC 22 is installed, which detects a change in magnetic force intensity through a positional movement with the magnet 24. The fixed latch 26, the magnet housing 23 provided inside the sensor housing 21 and provided with the magnet 24, and the sensor housing 21 are elastically provided between the magnet housing 23 and the sensor housing 21. An elastic member 25 for supporting is provided.

마그네트 하우징(23)은 일부가 센서 하우징(21)의 외부 타측으로 돌출되도록 형성된다. 이는, 마그네트 하우징(23)을 고정시키기 위함이다. 즉, 도 1에 도시된 바와 같이 센서 하우징(21)으로부터 노출된 마그네트 하우징(23)의 일부는 하우징 지지부(27)에 의하여 전자식 주차 브레이크의 외관을 형성하는 하우징(미도시)에 고정된다.The magnet housing 23 is formed such that a portion thereof protrudes to the outside of the sensor housing 21. This is to fix the magnet housing 23. That is, as shown in FIG. 1, a part of the magnet housing 23 exposed from the sensor housing 21 is fixed to a housing (not shown) that forms the appearance of the electronic parking brake by the housing support 27.

래치(26)는 센서 하우징(21)의 외부 일측으로 일정 부분 돌출되도록 센서 하우징(21)에 고정된다. 이때, 래치(26)는 베어링 모듈(30)에 의하여 너트부재(12)의 타단과 연결된다. 이에, 센서 하우징(21)은 래치(26)에 의하여 너트부재(12)의 이동에 따라 이동되도록 이루어진다.The latch 26 is fixed to the sensor housing 21 so as to partially protrude to an outer side of the sensor housing 21. At this time, the latch 26 is connected to the other end of the nut member 12 by the bearing module 30. Thus, the sensor housing 21 is made to move in accordance with the movement of the nut member 12 by the latch 26.

베어링 모듈(30)은 너트부재(12)와 연결된 연결축(32), 연결축(32)에 설치된 베어링(33), 베어링(33)과 함께 래치(26)를 감싸도록 이루어진 베어링 하우징(31)을 구비한다.The bearing module 30 includes a connecting shaft 32 connected to the nut member 12, a bearing 33 installed on the connecting shaft 32, and a bearing housing 31 configured to surround the latch 26 together with the bearing 33. It is provided.

베어링 하우징(31)은 센서 하우징(21)으로부터 돌출된 부분의 래치(26)를 잡아주도록 형성된다. 즉, 센서 하우징(21)은 너트부재(12)가 스크류부재(11)와 함께 상대운동시 베어링(33)에 의하여 회전력 및 축방향 변위가 직선운동으로 변환되어 래치(26)와 함께 이동하게 된다. 따라서, 래치(26)와 결합된 센서 하우징(21)이 이동하게 되더라도 마그네트 하우징(23)은 하우징 지지부(27)에 의하여 움직임이 제한된다. 이에 마그네트(24)와 홀 IC(22)의 상대 변위에 따라 주차 케이블(C)이 받는 힘의 세기를 검출하게 된다.The bearing housing 31 is formed to hold the latch 26 of the portion protruding from the sensor housing 21. That is, in the sensor housing 21, when the nut member 12 moves relative to the screw member 11, the rotational force and the axial displacement of the nut member 12 are converted into linear movements by the bearing 33 to move together with the latch 26. . Therefore, even if the sensor housing 21 coupled with the latch 26 moves, the magnet housing 23 is limited by the housing support 27. Accordingly, the strength of the force applied to the parking cable C is detected according to the relative displacement of the magnet 24 and the hall IC 22.

그러나, 상기와 같은 포스센서(20)는 주차 케이블(C)이 받는 힘의 세기를 측정하기 위하여 동력변환유닛(10)과 포스센서(20) 사이에 베어링 모듈(30)을 설치하고 이로부터 회전운동을 직선운동으로 변환하여 센서 하우징(21)을 이동시키는 구조로 이루어져야 하기 때문에 주차 케이블(C)의 제동력을 측정하기 위한 조립구조가 복잡하다는 문제점이 있다.However, the force sensor 20 as described above is installed from the power conversion unit 10 and the force sensor 20 to measure the strength of the force received by the parking cable (C) and rotates therefrom The assembly structure for measuring the braking force of the parking cable (C) is complicated because it must be made of a structure for moving the sensor housing 21 by converting the movement into a linear movement.

또한, 베어링 모듈(30)과 포스센서(20)를 연결하여 주는 래치(26)가 설치되어야 하는 구조 및, 포스센서(20)의 변위를 측정하기 위해 별도의 하우징 지지부(27)를 마련하여 마그네트 하우징(23)을 고정하여야 하는 구조에 따라 포스센서(20)의 형상 및 전자식 주차 브레이크의 형상이 복잡해지고, 조립 부품의 수가 증가하게 되어 조립 공정이 추가되는 문제점이 있다.In addition, the structure in which the latch 26 connecting the bearing module 30 and the force sensor 20 should be installed, and a separate housing support 27 is provided to measure the displacement of the force sensor 20 and the magnet. According to the structure to fix the housing 23, the shape of the force sensor 20 and the shape of the electronic parking brake is complicated, there is a problem that the number of assembly parts is increased and the assembly process is added.

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 주차 케이블의 제동력을 측정하는 센서의 구동 구조를 변경하고, 센서의 결합 구조를 단순화할 수 있는 센서유닛 및 이를 구비하는 전자식 주차 브레이크를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and provides a sensor unit and an electronic parking brake having the same that can change the drive structure of the sensor for measuring the braking force of the parking cable and simplify the coupling structure of the sensor.

도시된 바와 같이 구동기어(131)는 중간기어(132)와 맞물려 회전하며 중간기어(132)는 종동기어(133)와 치합되어 함께 회전한다. 이때, 종동기어(133)는 회전운동을 직선운동으로 변환하는 동력변환유닛(140)으로 동력이 입력되도록 한다. 즉, 종동기어(133)는 동력변환유닛(140)의 기어부재(143)와 치합된다.As shown, the drive gear 131 rotates in engagement with the intermediate gear 132 and the intermediate gear 132 is engaged with the driven gear 133 and rotates together. At this time, the driven gear 133 is a power is input to the power conversion unit 140 for converting the rotational movement into a linear movement. That is, the driven gear 133 is meshed with the gear member 143 of the power conversion unit 140.

동력변환유닛(140)은 감속기어유닛(130)에 연동하여 작동하면서 주차 케이블(C)을 당기거나 풀어주는 역할을 한다. 이러한 동력변환유닛(140)은 스크류부재(141)와, 스크류부재(141)와 나사 결합되는 너트부재(142)와, 너트부재(142)의 외면에 장착되는 기어부재(143)를 포함한다.The power conversion unit 140 operates in conjunction with the reduction gear unit 130 and serves to pull or release the parking cable (C). The power conversion unit 140 includes a screw member 141, a nut member 142 screwed with the screw member 141, and a gear member 143 mounted on an outer surface of the nut member 142.

기어부재(143)는 상술한 바와 같이 너트부재(142)의 외면에 장착되며, 이러한 기어부재(143)는 종동기어(133)와 맞물려 모터(120)의 구동력을 감속기어유닛(130)를 통해 전달받는다.The gear member 143 is mounted on the outer surface of the nut member 142 as described above, and the gear member 143 meshes with the driven gear 133 to reduce the driving force of the motor 120 through the reduction gear unit 130. I receive it.

스크류부재(141)는 일단에 연결부재(144)를 통해 주차 케이블(C)과 연결된다. 이러한 스크류부재(141)는 상술한 바와 같이 너트부재(142)와 나사 결합되는데, 이를 위해 스크류부재(141)의 외면에는 수나사부가 형성된다.The screw member 141 is connected to the parking cable C through one end of the connecting member 144. The screw member 141 is screwed with the nut member 142 as described above, for this purpose, an external thread is formed on the outer surface of the screw member 141.

너트부재(142)는 중공으로 이루어지며, 이 중공에 스크류부재(141)와 나사 결합을 위해 그 내면에 암나사부가 형성된다. 즉, 너트부재(142)와 나사결합된 스크류부재(141)는 너트부재(142)와 함께 상대운동하며 주차 케이블(C)을 동작시킨다. 이때, 너트부재(142)에는 도시된 바와 같이 스크류부재(141)가 삽입되는 방향으로 센서유닛(150)이 연결된다.Nut member 142 is made of a hollow, the female screw portion is formed on the inner surface for screwing the screw member 141 and the hollow. That is, the screw member 141 screwed to the nut member 142 moves relative to the nut member 142 and operates the parking cable C. At this time, the sensor unit 150 is connected to the nut member 142 in the direction in which the screw member 141 is inserted as shown.

센서유닛(150)은 동력변환유닛(140)의 작동에 의해 주차 케이블(C)이 받는 힘의 세기를 검출하여 그 신호를 전자제어유닛(160)으로 전달하는 역할을 한다. 본 발명에 따른 센서유닛(150)은 도 4에 도시된 바와 같이, 센서 하우징(151), 마그네트 하우징(153) 및 탄성부재(156)를 구비한다. 여기서 마그네트 하우징(153)은 너트부재(143)와 결합된 홀더(145)와 연결되는데, 상기 홀더(145)와 마그네트 하우징(153)의 결합구조는 아래에서 설명하기로 한다.The sensor unit 150 detects the strength of the force received by the parking cable C by the operation of the power conversion unit 140 and transmits the signal to the electronic control unit 160. As shown in FIG. 4, the sensor unit 150 according to the present invention includes a sensor housing 151, a magnet housing 153, and an elastic member 156. Here, the magnet housing 153 is connected to the holder 145 coupled with the nut member 143, and the coupling structure of the holder 145 and the magnet housing 153 will be described below.

센서 하우징(151)은 전자식 주차 브레이크(100)의 외관을 형성하는 액추에이터 하우징(110)에 고정되며, 내부에 마그네트(154)와의 위치 이동을 통한 자력 세기 변화를 감지하는 홀 IC(152)가 설치된다.The sensor housing 151 is fixed to the actuator housing 110 that forms the exterior of the electronic parking brake 100, and has a hall IC 152 installed therein that detects a change in magnetic strength through position movement with the magnet 154. do.

마그네트 하우징(153)은 센서 하우징(151) 내부에서 이동가능하도록 마련된다. 보다 구체적으로, 마그네트 하우징(153)은 상측에 자기장을 발생시키는 마그네트(154)가 설치된 마그네트 지지부(153a)와, 마그네트 지지부(153a)와 결합되어 센서 하우징(151)을 관통하여 외부 일측으로 일정 부분 돌출되도록 형성된 축부(153b)를 구비한다. 즉, 마그네트 하우징(153)은 센서 하우징(151) 내부에서 축부(153b)가 관통된 방향으로 이동가능하게 마련된다. 이때, 마그네트 하우징(153)과 센서 하우징(151) 사이에는 탄성부재(156)가 마련되어 마그네트 하우징(153)이 탄성부재(156)에 의해 탄성 지지된다.The magnet housing 153 is provided to be movable within the sensor housing 151. More specifically, the magnet housing 153 is coupled to the magnet support part 153a provided with the magnet 154 generating a magnetic field thereon and the magnet support part 153a to penetrate the sensor housing 151 to a predetermined portion to the outside one side. It has a shaft portion 153b formed to protrude. That is, the magnet housing 153 is provided to be movable in the direction in which the shaft portion 153b penetrates inside the sensor housing 151. In this case, an elastic member 156 is provided between the magnet housing 153 and the sensor housing 151 so that the magnet housing 153 is elastically supported by the elastic member 156.

이러한 마그네트 하우징(153)의 이동을 위하여 마그네트 하우징(153)에는 베어링(155)이 설치된다. 상기 베어링(155)은 센서 하우징(151)을 관통하여 돌출된 부분의 축부(153b)에 형성된 결합홈(153b')에 설치된다. 이러한 베어링(155)은 회전력 및 축방향 변위를 직선운동으로 변환시키는 역할을 한다. 도 3에 도시된 바와 같이, 마그네트 하우징(153)은 너트부재(142)에 결합된 홀더(145)와 결합된다. 홀더(145)는 일단이 너트부재(142)의 타단과 결합되어 함께 회전하도록 이루어지며, 타단은 축부(153b) 및 베어링(155)을 감싸며 베어링(155)을 잡아주도록 형성된다. 따라서, 너트부재(142)가 스크류부재(141)와 상대이동시 홀더(145)와 연결된 마그네트 하우징(153)은 너트부재(142)와 함께 이동하게 된다.In order to move the magnet housing 153, the magnet housing 153 is provided with a bearing 155. The bearing 155 is installed in the coupling groove 153b ′ formed in the shaft portion 153b of the portion protruding through the sensor housing 151. The bearing 155 serves to convert rotational force and axial displacement into linear motion. As shown in FIG. 3, the magnet housing 153 is coupled to the holder 145 coupled to the nut member 142. One end of the holder 145 is coupled to the other end of the nut member 142 to rotate together, and the other end is formed to surround the shaft portion 153b and the bearing 155 and hold the bearing 155. Accordingly, the magnet housing 153 connected to the holder 145 when the nut member 142 moves relative to the screw member 141 moves together with the nut member 142.

그러면, 상기와 같은 구조를 갖는 전자식 주차 브레이크(100)를 통해 제동시 센서유닛(150)이 주차 케이블(C)의 제동력을 측정하는 상태에 대해 설명하기로 한다.Then, the state in which the sensor unit 150 measures the braking force of the parking cable C when braking through the electronic parking brake 100 having the above structure will be described.

먼저, 모터(120)가 작동하여 모터(120)로부터 발생된 회전력을 감속기어유닛(130)을 통해 전달받은 동력변환유닛(140)은 회전운동을 직선운동을 변환시키게 된다. 즉, 도 5에 도시된 바와 같이, 너트부재(142)가 회전하면 너트부재(142)와 나사결합된 스크류부재(141)가 너트부재(142)의 내부로 삽입되어 들어가면서 스크류부재(141)에 연결된 주차 케이블(C)이 당겨진다. 동시에 너트부재(142)는 스크류부재(141)의 이송 반대방향으로 동일 변위만큼 이동하게 된다.First, the motor 120 operates to receive the rotational force generated from the motor 120 through the reduction gear unit 130, and the power conversion unit 140 converts the rotational movement into a linear movement. That is, as shown in FIG. 5, when the nut member 142 rotates, the screw member 141 screwed with the nut member 142 is inserted into the nut member 142 to enter the screw member 141. The connected parking cable (C) is pulled out. At the same time, the nut member 142 is moved by the same displacement in the opposite direction of the transfer of the screw member 141.

이에 너트부재(142)의 타단과 결합된 홀더(145) 및 홀더(145)와 연결된 마그네트 하우징(153)이 탄성부재(156)를 압착하며 이동하게 된다. 이때, 마그네트 하우징(153)은 너트부재(142)의 이동시 베어링(155)에 의하여 회전력 및 축 방향 변위가 직선운동으로 변환되어 용이하게 이동하게 된다.Accordingly, the holder 145 coupled to the other end of the nut member 142 and the magnet housing 153 connected to the holder 145 compress and move the elastic member 156. At this time, the magnet housing 153 is easily moved by the rotational force and the axial displacement is converted to linear movement by the bearing 155 when the nut member 142 is moved.

한편, 센서 하우징(151)은 액추에이터 하우징(110)에 고정된 상태로 마련됨에 따라 마그네트 하우징(153)이 이동하게 되면, 홀 IC(152)는 마그네트(154)의 위치 이동을 통한 자력 세기 변화를 감지해 주차 케이블(C)이 받는 힘의 세기를 검출하게 된다. 여기서 검출된 신호는 전자제어유닛(160)으로 전달되고, 전자제어유닛(160)은 검출된 신호에 따라 모터(120)의 구동을 제어하게 된다.Meanwhile, when the magnet housing 153 is moved as the sensor housing 151 is fixed to the actuator housing 110, the hall IC 152 changes the magnetic force intensity through the position movement of the magnet 154. It detects the strength of the force received by the parking cable (C). The detected signal is transmitted to the electronic control unit 160, and the electronic control unit 160 controls the driving of the motor 120 according to the detected signal.

제동 해제시, 모터(120)의 역회전에 따라 너트부재(142)와 스크류부재(141)가 제동 시의 반대방향으로 이동하게 되면, 마그네트 하우징(153)은 탄성부재(156)의 탄성력에 의하여 원래의 위치로 용이하게 복귀할 수 있게 된다.When the braking is released, when the nut member 142 and the screw member 141 move in the opposite directions when braking according to the reverse rotation of the motor 120, the magnet housing 153 is moved by the elastic force of the elastic member 156. It is possible to easily return to the original position.

결과적으로, 본 발명에 따른 센서유닛(150)은 마그네트 하우징(153)을 이동시키며 주차 케이블(C)이 받는 힘의 세기를 측정하도록 구조를 개선하고, 너트부재(142)의 회전 이동에 따른 회전력 및 축 방향 변위를 직선운동으로 변환하는 기존 베어링 모듈(도 1의 '30' 참고)의 기능을 센서유닛(150)이 행하도록 함으로써, 종래의 포스센서(도 2의 '20' 참고)에 비하여 구조가 단순화되었다. 또한, 본 발명에 따른 센서유닛(150)을 채택함으로써, 기존의 마그네트 하우징(도 2의 '23' 참고)을 고정시키기 위한 별도의 고정부재(도 1의 '27' 참고)를 구비하여야 하고, 이에 따라 센서 하우징 및 전자식 주차 브레이크의 하우징의 구조가 복잡해지는 문제점을 해결할 수 있게 된다.As a result, the sensor unit 150 according to the present invention improves the structure to move the magnet housing 153 and measure the strength of the force received by the parking cable (C), the rotational force according to the rotational movement of the nut member 142 And the sensor unit 150 to perform the function of the existing bearing module (see '30' of FIG. 1) for converting axial displacement into linear motion, as compared to the conventional force sensor (see '20' of FIG. 2). The structure is simplified. In addition, by adopting the sensor unit 150 according to the present invention, it should be provided with a separate fixing member (see '27' of FIG. 1) for fixing the existing magnet housing (see '23' of Figure 2), Accordingly, the structure of the sensor housing and the housing of the electronic parking brake can be solved.
